                        TITLE 21--FOOD AND DRUGS
 
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF 
 
PART 310_NEW DRUGS--Table of Contents
 
        Subpart E_Requirements for Specific New Drugs or Devices
 
Sec. 310.531  Drug products containing active ingredients offered
over-the-counter (OTC) for the treatment of boils.

    (a) Aminacrine hydrochloride, benzocaine, bismuth subnitrate, 
calomel, camphor, cholesterol, ergot fluid extract, hexachlorophene, 
ichthammol, isobutamben, juniper tar (oil of cade), lanolin, magnesium 
sulfate, menthol, methyl salicylate, oxyguinoline sulfate, petrolatum, 
phenol, pine tar, rosin, rosin cerate, sassafras oil, sulfur, thymol, 
triclosan, and zinc oxide have been present in OTC boil treatment drug 
products. There is a lack of adequate data to establish general 
recognition of the safety and effectiveness of these or any other 
ingredient for OTC use for the treatment of boils. Treatment is defined 
as reducing the size of a boil or reducing an infection related to a 
boil. Treatment has involved the use of ``drawing salves'' for these 
purposes. These ``drawing salves'' contained various ingredients. Based 
on evidence currently available, any OTC drug product offered for the 
treatment of boils cannot be considered generally recognized as safe and 
effective.
    (b) Any OTC drug product that is labeled, represented, or promoted 
for the treatment of boils is regarded as a new drug within the meaning 
of section 201(p) of the Federal Food, Drug, and Cosmetic Act (the act), 
for which an approved application or abbreviated application under 
section 505 of the act and part 314 of this chapter is required for 
marketing. In the absence of an approved new drug application or 
abbreviated new drug application, such product is also misbranded under 
section 502 of the act.
    (c) Clinical investigations designed to obtain evidence that any OTC 
boil treatment drug product is safe and effective for the purpose 
intended must comply with the requirements and procedures governing the 
use of investigational new drugs set forth in part 312 of this chapter.
    (d) After May 7, 1991, any such OTC drug product that contains 
aminacrine hydrochloride, bismuth subnitrate, calomel, camphor, 
cholesterol, ergot fluid extract, hexachlorophene, isobutamben, juniper 
tar (oil of cade), lanolin, magnesium sulfate, menthol, methyl 
salicylate, oxyguinoline sulfate, petrolatum, phenol, pine tar, rosin, 
rosin cerate, sassafras oil, thymol, or zinc oxide initially introduced 
or initially delivered for introduction into interstate commerce that is 
not in compliance with this section is subject to regulatory action.
    (e) After May 16, 1994, any such OTC drug product that contains 
benzocaine, ichthammol, sulfur, or triclosan initially introduced or 
initially delivered for introduction into interstate commerce that is 
not in compliance with this section is subject to regulatory action.
    (f) This section does not apply to drug products that contain 
benzocaine labeled, represented, or promoted for OTC topical use in 
accordance with part 348 of this chapter.
